- Documentation on language does not have an explicit section on adding comments.
- Nice to have tips for syntax-highlighting inside Kv files for PyCharm
- Thanks @kjell for pointing out [PyCharm settings](https://github.com/kivy/kivy/wiki/Setting-Up-Kivy-with-various-popular-IDE's#kv-lang-auto-completion-and-highlighting)
- The resulting game is quite sluggish... maybe framerate issues?
